- Abstract
Fusarium wilt is the most destructive soil-borne disease that poses a major threat to chickpea production. To comprehensively understand the interaction between chickpea and Fusarium oxysporum, the xylem-specific transcriptome analysis of wilt-resistant (WR315) and wilt-susceptible (JG62) genotypes at an early timepoint (4DPI) was investigated. Differential expression analysis showed that 1368 and 348 DEGs responded to pathogen infection in resistant and susceptible genotypes, respectively. Both genotypes showed transcriptional reprogramming in response to Foc2, but the responses in WR315 were more severe than in JG62. Results of the KEGG pathway analysis revealed that most of the DEGS in both genotypes with enrichment in metabolic pathways, secondary metabolite biosynthesis, plant hormone signal transduction, and carbon metabolism. Genes associated with defense-related metabolites synthesis such as thaumatin-like protein 1b, cysteine-rich receptor-like protein kinases, MLP-like proteins, polygalacturonase inhibitor 2-like, ethylene-responsive transcription factors, glycine-rich cell wall structural protein-like, beta-galactosidase-like, subtilisin-like protease, thioredoxin-like protein, chitin elicitor receptor kinase-like, proline transporter-like, non-specific lipid transfer protein and sugar transporter were mostly up-regulated in resistant as compared to susceptible genotypes. The results of this study provide disease resistance genes, which would be helpful in understanding the Foc resistance mechanism in chickpea.
